I did use the apropos command and found those commands plus some others
that seemed to be what I needed. I asked Lucid for further
details on these commands (as they are undocumented) and they advised me
not to use any undocumented features as they are not for general use and may
be altered in later releases.
I would therefore appreciate any further help on whether to use these commands
or not and if so any examples on their use.
If it is unadvisable to use these commands I wish people would check carefully
whether the commands they recommend can be used without having adverse side
effects and therefore not recommend them.
BTW I'm using Lucid Common Lisp 4.0 and Clim 1.1 on a SparcStation running
